Components are not loaded and shown properly when there are concurrent calls to NavigatorController.present()

Short description of the problem:

When there are concurent calls to NavigatorControllers present() method, some of components don’t properly loaded and shown, e.g.:

nav.present(loading);
nav.present(toast);

It seems that the last call to present() prevents all the previous calls to present().

What behavior are you expecting?

Both of loading and toast components are loaded and shown properly and promises from present method resolve as they should do. After 1500ms loading component should be dismissed.

Steps to reproduce:

In all three cases expected behavior is the same and described in the section above.

Open plunker page for demos.

Case 1:

Click Start button

• Move your mouse over the Start button and you will see, that there is a transparent overlay.
• this.nav.present(loading) isn’t resolved

Case 2:

Open home.ts file and comment ‘Case 1’ code and uncomment Case 2 code. Click Start button.

• Loading dialog is shown, but it won’t be removed after 1500 ms
• this.nav.present(loading) isn’t resolved

Case 3:

Comment ‘Case 2’ code and uncomment Case 3 code. Click Start button.

• Loading dialog isn’t shown
• this.nav.present(loading) is resolved

Other information: I think #6209 can somehow be related to this issue, but I’m not sure. #7342

@likerRr Sorry for not being clear! You will be able to show a loading and toast component at the same time, but not multiple overlay components of the same type at the same time. Thanks!

@jgw96 Hello, thanks for answering. Please, clarify, you mean that in beta.11 I won’t be able to show loading and toast components at the one moment? Even if I wait until one of them resolves?
